so many things haha, that isn't to say Im right or that other people wouldn't also hate my work!
however I think my main hates are;
Underdeveloped characters, when someone has put some effort in to making the short, but they obviously haven't thought about the characters, or what they are doing in the film.
as zen said, slow pacing gets to me big time, as does leaving a shot to continue way too long, such as having someone walking away from the camera for like 30 seconds haha.
And my biggest pet hate, is people writing scripts around ideas or places or people that they dont know, Basically i mean someone from manchester or somewhere random writing a script about CIA agents in wisconsin in winter, or anything like that. People need to remember to write about what they know, not just guess what wisconsin looks like in the winter, then just film it in some woods.

I didnt mean to rant, but I have some really talented short film makers, even some real beginners yet they are always let down by quite simple things, things that can usually be avoided early on in pre production, however this is not to say that I havent made each and every one of these mistakes, even if half the time I dont realise it haha!
